Jakarta ee 永久性RMI客户端连接问题

我对RMI技术完全陌生，但我逐渐将其视为构建真实世界分布式应用程序的非常重要的中间件体系结构。我在尝试将客户端程序连接到服务器程序时遇到的挑战将我带到了这个站点。我之前所做的一段代码一直给我java.rmi.ConnectException…无法承载127.0.0.1。实际上，我打算先在本地运行这些程序。所以所有的程序都在同一台计算机和文件夹中。我的操作系统是Windows7

我遵循了从其他论坛得到的指令/建议，但错误依然存在。我遵循的指令包括 1运行服务器程序时引用rmi.server.hostname属性

2编辑\etc文件夹下的主机文件夹

同样的异常仍然存在。RMI程序是通过从客户端调用的sayHello方法打印的基本Hello world。现在有人把下面的代码贴给我。我尝试从客户端程序连接，将主机名、端口号和字符串文本作为运行时参数传递，这次持续存在的异常是java.rmi.UnknownHostException..我很想解决所有这些问题，以尝试更大的项目。如果有人能提供线索，我将不胜感激
